Dead on accuracy. I was placing shot on top of shot with my m98 using Team colors paint, at 285 fps. I would say a distance but im not good with judging. Lets just say every time i aimed it it hit the mark, longer ranges its slightly worse but not by much.
The only thing i can say that i have seen wrong with it is it is kinda loud, but i mean on a speedball field it doesnt matter since you can see the people anyways, umm...also my friends autospirit wouldnt work to well on TC and break a couple
i like this barrel alot, its light so it doesnt weigh down my gun, Its accurate so i can get those much needed barrel or hopper hits, and its farely cheap ( around $60). I dont mind the noise, and dont really notice it much when im in the mix of things. I got a Smart Parts Progressive from a friend who sold his m98 and i can clearly say that the Autospirit is way more accurate than the Progressive, it is louder as i said before but u cant really notice it that much. I think accuracy matters more than noise anyday, so i would definately buy an autospirit over a Progressive. i give it a 9 because i havent tried an AA or freak,also i havent tried any dye's, so i cant say that its the very best but i can say its definately up there.
